for the front suspension, do i also need to change the disc calipers? cos disc on 150 is installed differently while comparing the 200 n 220....

the swing arm, i just know that its a bit longer than the siblings, does it reduce the wobble at the high end?

my current rear tire is a 140/70, i'm currently happy with the swingarm and i've not thought about the change there, please through some more light..

moreover i'm not switching to the chains of 220's or its sprocket.. is it advisable to run the chain naked?

So stop it and dont do the engine mod... and even if you do remember that your body may not have that aerodynamics and stop power to ho;d that engine down under pressure (you may loose control)...

So dont buddy.. dont...

comeon bro... aerodynamics..! a stock 150 does 120 and a stock 220 does 135.... 15kms and aerodynamics....

my bike, a month ago did 125kmph on the speedo with my add-ons so in my opinion, i dont want to get aerodynamics in..

@Ganesh: It will be good no doubt. I wud though recommend a 200 kit than a 220 kit, reason being the 200 will rev much better than the 220 as 220 has a longer stroke. And the current disc/tire/swingarm etc setup are more than enough. Dont mess with all that. As for the chain-sprocket I would recommend going to 40-42. Will give decent mid and top end. Get the BS29 carb tuned properly and it will work fine. Also IIRC the val;ve setups are different.

P.S: A word of advice. Am not sure of ur local mech's expertise. I would much rather recommend Raju Sir(as ur at Chennai). He's already done the same thing on prashanth_benz's bike.

got a doubt here... in my opinion, 200's feels kind off lazy, but tat i never felt with the 220...what is the difference..??

and a big NO! work is not done by a local mechanic... i'm doin it fom CBX racing..

thanks for the advice on the misc. parts though...

btw, do i really need to change the sproket, already i have my free flow working in the mid-high end.... :confused

and yeah, i spoke to prashanth about it.

hi,
I'm intend to get my engine upgraded to a 220 engine from my current 150cc UG2... its not a straight fit though... alterations are there...

as per my mechanic, i need to change:
1. piston+bore
2. gearbox(ratio)
3. clutches
4. Suspension adjustment
5. manifold(no idea here)
6. crankshaft
7. 29mm carbuerettor
(he mentioned some more too, i dont remember)

please enlighten me in this context... i dont want to look a complete fool in front of my mechanic...

i was quoted a price of 22k... is it worth?

I'm sure your mechanic doesnt have the capability , the kind of training or the kind of facility to pull this off even if he is one of the best in India. Dont try anything like this. Either stick to your existing bike or sell this and get a new one.

@Aparajith: i'll be changing my sprocket based on my gear ratios... if i find it over revving, then i would go for the 200's front sprocket.. but rear, i still hav to see once the job is done..

iso u r also goin for the 200 kit??? if yes then personal experience,
the current ug3's 44t rear set up is extremely torquey, the top end at 10k rpm that i am getting is 121!! where as the previous stock ws givin me 126 and on a gradient it used to go to 130...the poit is go for 200's stock chain sprocket . its a 38t rear set up.am gettin one asap. just 850 bucks dude. otherwise u need to get a custom sprcoket wich costs above 1k...not worth it, coz u need to alter ur chain then. I & aprajith had a long talk bout this as well.

& DUDE ur gear ratios are going to be decided by ur sprocket man!!

Apara...how are u??? my bikes a crotch rocket now. smokd all the bikes in the vicinity, got bosch HID(fcukd my battery man!) still waitin to upjet.

SAberc*Oot

\v/ peace, anyways he is not fitting an R1's engine in pulsar150 yaaar. calm down it can be done in any garage. Just that the mech needs to know wat he is doin.

**undefineme3** · 05-04-2009, 06:42 PM

not goin for the 200's kit... am still stickin to the 220

... i first want to try it with my current sprocket and then based on the response from the bike i intend to change... as of now i'm not changing any of the sprockets... the first priority is to get the engine fixed, then i would eye the rest of the setup...
the first thing i look for is the initial pickup, so i thought, why dont i try my current sprocket n then c if i need to change it...

a 150cc having contents of a 220cc with a sprocket of a 200cc.... man i'm loving it... the only thing i missed out is a 180....

by the way, mine is not the UG3, its the UG2

**Aparajith** · 05-05-2009, 08:11 PM

@rossi: Doing great man. Yeah, what did I tell u, Pulsars typically have great low and mid but pathetic top. With a higher cc only low-end torque is improved. For top end u need revised gearing aka sprocketting

@Ganesh: U need better performance? My sincere advice chuck that 140 section rear and get a 100 section. Max my advice would be to get a 120 section. Anything more and ur giving up a lot. And the reason the 200 has a poorer low-end than the 220 is because it is a short stroke than the 220 and needs to be revved to its power band. Hence its got a shorter gearing than the 220. The 220 being a longer stroke is more torquier. I would still advice a 200 kit as its simpler. The 220 might be a hassle. Anyway nothing wrong in giving it a shot and if u succeed, u might well be the first one to have done it. Not to mention, it would feel great.

ALL THE BEST!!!

As u r happy with ur current swigram we can think changing it as a secondary option..If u r changing the rear sock's to that of 220 u have to cut the current chain cover a little.. no other mod required. It is not recomanded to run ur current chain as open unless u change to O ring.. As ur tyre is very wider it is more than enough to get stability at 135Km/hr in speedo..

I think u have to change ur calipers to accomodate ur disk or have to do some welding work.. As I have done some welding work to accomodate RTR disc in apache 150.. It was done by a TVS mechanic.. ALL THE BEST dude..

**undefineme3** · 05-05-2009, 10:21 PM

@Aparajith: yes, i'm desperately searching for a decent 100/90-17.... i contacted MRF alwarpet and they dont seem to have stock of MRF zapper-Q...

on the other hand, i may go back to my old dunlop which i still have(120/80) with me...

PS: can i go for ceat or metro continental??

update on the bike:
today the bike is totally dismantled...

**Aparajith** · 05-05-2009, 10:28 PM

U want the best 100-section in the market today? Forget everything and get the R15 tires! Else yeah CEAT/DUNLOP/MRF are good enough. I dont go too much into the specifics like tires man, sorry. Check the tires thread.

**themadrussian** · 05-06-2009, 03:49 PM

can be done easily under 15K

**me is rossi** · 05-06-2009, 07:42 PM

@unde....y r u behind changin the swingarm yaar???wats the big deal?? and is the 220 engine directly fitting??

**undefineme3** · 05-06-2009, 08:27 PM

@me is rossi: na... i'm not changin the swing arm.... i really didnt c a point to change my swing arm... am happy with the current one itself... the difference is in a length and width increase of 1cm i suppose....

couldnt make it to the workshop today... tomo got my semester exams...
